Abstract

The hyperfine magnetic fields and their temperature dependence for ¹⁸¹Ta in ErFe₂ and TmFe₂ have been measured by the TDPAC method. Respectively, the following values were obtained at T ≈ 80 K: 16·3(2) T and 17·6(2) T. These data complete those for other RFe₂ Laves phases (except CeFe₂) obtained earlier and are discussed in common in the framework of the model predicting the induction of the localised 5d moment at Ta ions due to 5d-3d band hybridisation enhanced by the 4f-5d interaction.
